-'0 all whom it may concern.-

vention is fully disclosed in the following description and claims.

- Referring to the said drawings, Figure 1 is a plan view of the blank from which the box embodying my invention is formed. Fig. 2,

. Fig.8, and Fig. 4 show the successive steps taken in folding up the blank to form the collapsedbox. Fig. 5 is a perspective view of the expanded box. Fig. 6 is a plan view of the same, on a reduced scale. Fig. 7 is a sectional view taken on the line 2 z of Fig. 5, showing the position of the bottoms in the act of expanding the box just before the bottoms have been brought to their'final position.

My invention relates particularly to folding paper boxes of tra ezoidal form known in the trade as pail-fi lers, the dimensions of the said boxes being such that a number of the said boxes be placed within a pail or other circular receptacle with their longer sides dis osed radially thereto, so as to completely l the circular space within such receptacle and my invention has for its object to form such a box from a blank, so that it may be folded flat for shipment and may be unfolded and placed in operative condition when desired.

Referring to the drawings, Fig. 1 represents a plan view ofthe blank from which the box is made before folding, said blank being made of paper or cardboard of the desired thickness and cut and scored to form the following parts.

Arepresents the exterior bottom section, which is of trapezoidal form and is providedwith a diagonal score a, upon which it may be folded.

B and O are the longer sides of the box, formed integrally with the bottom section A by extending its two longer edges. D and E are the two shorter sides of the box and are integral with the sides B and C, respectively, being of the same height as said sides B and a pasting-flap for the purpose.

O and of the same width as the of the bottom section A. v 1 F is the interior bottom section, which i of the same size as the exterior bottom section A and is made integral with one of the short side sections D E, in this case the short side section D, and is scored diagonally from the outer corner of the side section D as shown at f, to enable it to fold substantially cen trally. The interior bottom section Fis also shorter edges provided on its longer edges with flapsf and f, which when the box is formed fold up against the inner faces of the side sections B O and by contact therewith hold the bottom section F firmly in position and also brace the sides B and O. The other short side section E is provided with a bottom looking-flap G, integral therewith at its bottom edge; as

shown, which when the box is formed lies between the exterior bottom section A and the interior bottom section F and is held by contact therewith, thus bracing the side section E, which is the only one not connected integrally with one or the other of the bottom sections.

To form the box, it is necessary to unite the adjacent edges of sections B O and D E, one of the meeting edges being provided with In this in stance the sections B and D are each provided with a pasting-flap b and d, respectively. To form the box from this blank, the interior bottom locking-flap G is turned inward to lie upon the side section E, and the interior bottom F is folded upon itself on line f and is then folded uponthe side section D. The side sections O andE are then turned over upon the sections B D, folding on the scored line a of exterior bottom A,

- and the pasting-flaps b and d are pasted to the side sections O and E, respectively. Both of these pasting-flaps are on the same side, as will be seen in the drawing, thus expediting the pasting o eration, and it is only necessary to paste t ese two flaps.

In expanding the collapsed or folded box the sides B, O, D, and E are moved a art, thus raising the exterior bottom A into orizontal position. The bottom flap G is then pushed down upon the bottom A, and the in terior bottom F is then pushed down upon flap G and exterior bottom A, the lateral flaps ff thereof being bent upward and enga ing the sides B and O.

t will be seen that the box has two bottom sections A and F, each of which forms a side complete bottom for the box. The bottom A is integral with two sides B and C, and the bottom F is integral with one side D, thus firmly uniting the sides when the bottoms are in operative position, and the side E which is not connected to the said bottoms is rovided with the fla G, which is firmly held between the two bottoms and thus braces and secures the remaining side.

What I claim, and desire to secure by Letters Patent,is-

- 1.. A ank for a collapsible box having sections, a bottom ection united to. two

sides, an auxiliary bottom section of the same size as the main bottom section united to anoth rside and adapted to fold upon the m n bottom. when the bo is expanded, sub:

stantially as described.

2. A blank for a collapsible box having ide sections, a main bottom section united to two of the side sections, an auxiliary bottom section of the same size as the main bottom section united to anotherside section main bottom when the .ox is expanded, said auxiliary bottom section being provided with lateral flaps to engage the side sections, substantially as described.

4. A blank for a collapsible box having side sections, a main bottom section united to two. of the side sections, an auxiliary bottom section of the same size as the main bottom section united to another side section and a bottom flap united to another side section and adapted to lie between the bottom sections when the box is expanded, said auxiliary bottom section being provided with lateral flaps to engage the side sections, substantially as described.

5. A four-sided collapsible paper box, having an interior and exterior quadrilateral bottom and two of whose sides are for-med by extensions of adjacent edges of one of said quadrilaterals, the second two sides being formed by extensions of the outer side edges of the first sides, and the other quadrilateral bottom" projecting down from the bottom edge of one of the second sides and a flap projecting down from the bottom edge of the other of said second sides, substantially as described.

6. Aiour-sided collapsible paper box, hav-. ing an interior and exterior quadrilateral bottom, two of whose sides are formed by extensions of adjacent edges of one of said quadrilaterals, the second two sides being formed by extensions of the outer side edges of the first sides, two glue-flaps, one upon the side edge of one of the first, the other upon the side edge of one of the second sides, and the other quadrilateral bottom projecting down from the bottom edge of one of the second sides, substantially as shown and (10-.

scribed.
